In which process is heat capacity infinite for ideal gas?
AAdiabatic
BIsochoric
CIsothermal
DIsobaric
Answer & Solution
Correct answer: C. Isothermal
Heat capacity C = dQ/dT. In ISOTHERMAL, dT = 0 even with dQ ≠ 0 (heat absorbed but T unchanged). So C → ∞. In adiabatic dQ = 0 regardless of dT, so C = 0.
